Product Description

ERNiCrMo-3 Nickel Alloy Welding Wire
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a premium nickel-chromium-molybdenum alloy that boasts precise elemental formulation, ensuring unmatched performance:

• Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
• Impurities: Minimizes risks with ultra-low iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) content

2. Mechanical Properties

• Tensile Strength: Achieves ≥760 MPa, ensuring robust durability.
• Yield Strength: Offering resilience with ≥420 MPa.
• Elongation: Provides flexibility with ≥27% elongation.
• Impact Toughness: Exhibits high resistance to fatigue and stress corrosion cracking, suitable across a range from cryogenic to high-temperature conditions.

3. Physical Properties

• Density: Rigorously maintained at 8.4 g/cm³.
• Melting Range: Withstands temperatures between 1290-1350°C.
• Structure: Features a face-centered cubic lattice, transitioning to stable Ni3(Nb,Ti) phases post heat treatment at ~650°C.

4. Key Features

• Corrosion Resistance: Unmatched resistance to pitting, crevice corrosion, and stress corrosion cracking, even in harsh chloride, acidic, and marine conditions.
• High-Temperature Stability: Superior strength and oxidation resistance, unwavering up to 1800°F (982°C).
• Versatility: Expertly suited for welding diverse metals (e.g., carbon steel to nickel alloys) and for surface cladding.

5. Welding Process Compatibility

• Methods: Perfectly compatible with TIG (GTAW), MIG (GMAW), submerged arc (SAW), and plasma arc welding.
• Shielding Gas: Utilizes argon or argon-helium mixtures for TIG/MIG; recommends INCOFLUX 7 flux for SAW.
• Wire Diameters: Available in 0.8-3.2 mm sizes (both spooled and straight rods).

6. Applications

• Industries: Widely used across aerospace (engine components, exhaust systems), chemical processing (reactors, pipelines), marine (valves, seawater systems), and oil/gas industries (wellhead equipment).
• Materials Welded: Perfect for welding INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and dissimilar metal combinations (e.g., nickel alloys to stainless steel).

7. Standards & Certifications

• AWS/ASME: Fully compliant with AWS A5.14, ASME SFA-5.14, and UNS N06625 standards.
• Certifications: Holds prestigious ABS, NADCAP, and ISO 18274 certifications crucial for high-stakes industries.

8. Handling & Storage

• Moisture Control: Ensure ultimate storage conditions by keeping the environment dry; our copper-coated variants significantly enhance conductivity, ensuring superior performance.
• Pre-Weld Prep: Prior to welding, meticulously clean surfaces to remove oil, rust, and moisture. Employ low heat input to expertly avert embrittlement, guaranteeing the integrity of your welds.

9. Packaging & Availability

• Packaging: Available options include convenient spools weighing between 5-15 kg or precisely aligned straight rods, catering to diverse industrial needs.
• Lead Time: Our efficient logistics ensure your orders typically ship within an expedited timeframe of 3-15 days, adjusted based on the quantity required.

Summary: Our ERNiCrMo-3 Nickel Alloy Welding Wire stands as a superior choice for challenging environments, with its unmatched mechanical strength, exceptional corrosion resistance, and versatile application across numerous industries.
